Benishek barely leads McDowell, 40 percent to 38 percent, with 22 percent of respondents undecided, according to a survey paid for by House Majority PAC, a Democratic super PAC, and released to Roll Call.

The poll is the most recent indication Democrats can compete in the northern Michigan House district this cycle. It's one of the must-win seats for House Democrats if they want to make inroads into the GOP's 25-seat majority this November.

Former Rep. Bart Stupak (D) held the 1st district seat for nine terms before retiring in 2010. Last cycle, Benishek defeated McDowell by 11 points in their first matchup.
